CONDENSER- Specification of Letters Patent.

Patented June 26, 1906.

To all whom it may concern.-

Be it known that I, WILLIAM SOHWANHAUS- SER, a citizen of the United States, residing at the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Im rovements in Condensers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

. The object of the present invention is to provide improved means for collecting and cooling the air and uncondensed vapors in the condensing-chamber of that class of condensing systems in which the air and uncondensed vapors or part of these are removed from the condensing-chamber separately from the discharge water, the especial object of the invention being to provide a simple, chea and compact construction by which an e cient cooling action shall be secured by liquid-cooled surfaces.

For a full understanding of the invention a detailed description of constructions embodying all the features of the same as applied in preferred forms will now be given in connection with the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a diagrammatic elevation of a condenser system embodying the invention as applied to a common type of gravity injector condenser system. Fig. 2 is a central vertical section of the condensing-chamber and air-cooler. Figs. 3 and 4 are horizontal sections of the air-cooler on lines 3 and 4 of Fig. 2. Fig. 5 is a section of the air-cooler similar to Fig. 2, showing a modification. Figs. 6 and 7 are sections on the'lines 6 and 7 of Fig. 5. Fig. 8 is a section similar to Fig. 6, showing a modified form of air-passages.

In the drawings, A is the condensingchamber; B, the steam-pipe entering at the to C, the condensing-water pipe through wliich the condensing water is forced by the circulating-pump D, and E the air-pipe through which the air and uncondensed vapors are drawn off by air-pump F. The condensing-water pi e O enters the lower part of the condensing-c amber A and extends upward centrally of the chamber, the water being delivered from its upper end past an adjustable spray-nozzle G, which is ribbed vertically on its periphery and carried by a vertical rod 10, movable vertically for adjustment of the nozzle G by being screw-threaded through a stufiing-box 11 in the steamgripe elbow, as usual in such constructions.

the parts thus far described are shown as of a form common in this class of condensers; but it will be understood that they may be of any other suitable form.

Referring now to the means and cooling the air and uncondensed vapors, to which the present invention especially relates, there is mounted on top of the condensing-water pipe C, so that the condensing water passes upward through it to the spraynozzle G, an air-chamber H, extending over a considerable part of the condensing-chamber and which receives upon its lower side, preferably through an air-inlet 12, as shown, the air and uncondensed vapors arising from the lower part of the condenser within the space between the falling condensing Water and the condensing-water pipe O.

The top and side walls of the air-chamber E are preferably curved, as shown, so as to form a hood or bell, and the chamber is provided with a central passage 13, forming a continuation of the condensing-water pipe 0 and through which the water passes to the spray-nozzle G, the upper part of the air- 0 amber being provide with ribs 14, forming slots similar to those of the ordinary spray ipe through which the Water is spraye out sidewise past the spray-nozzle G, so as to fall in a shower upon the top of the air-chamber H and within the space surrounding the air-chamber. These ribs 14 may be continued over the top and side walls of the air-chamber, as shown, for distributing the Water or may be of such extent only as to form a spray end of the passage 13, or this spray-pipe for coacting wlth the spray-nozzle G may be otherwise formed.

The air-chamber Hwmay be provided only with the central water-passage 13 and all the water from the condensing-pipe C passes through this; but for securing a more efficient cooling action it is desirable that the water shall be applied so as to coolthe opposite side walls of air-passages in the chamber H, and this result is secured in the construction shown in Figs. 1 to 4 by providing a water passage or chamber 15, curved outward from the top of the pipe 0 around a central horizontal deflecting-plate l6 and then infor collecting ward and upward to the spray-delivery, outside of which water passage or chamber 15 is the inner wall of the air-passages, so that this inner wall of the air-passages is thus efiiciently cooled. by the condensing water in addition to the cooling of the outer wall of the air-passages by the water sprayed upon the top and side walls of the air-chamber. The construction shown provides also for adjusting the spray-nozzle G down into the passage 13, so as to limit the amount of water passing through the passage 13 without choking substantially thepassage 15, so that water for cooling the air is always provided even though little condensing water be required. The air-chamber H is divided by vertical partitions 17 into air-passages 18, through which the air is conducted in a tortuous course from the air-inlet 12 to the air-outlet 19, which latter outlet 19 is connected to the air-pipe E, the air and uncondensed vapors thus remaining in contact with water cooled by surfaces in the air-chamber for a considerable time, thus securing an efficient action with a very compact air-cooler. A dripopening 1 may be provided in the bottom of the air-chamber, through which any condensation from vapors in the air-passages will 7 return to the condensing-chamber.

In the construction shown in Figs. 1 to 4 these air-passages 18 are circular and concentric, the successive passages being con nected by openings diametrically opposite each other, so that the air enters on one side of the chamber and leaves it at the opposite side, as shown by the plain arrows in Figs. 3 and 1, thus securing a long course of the air from the inlet 12 to the outlet 19. The course of the water in Fig. 4 as well as in Fig. 1 is shown by the feathered arrows.

The construction shown in Figs. 5, 6, and 7 is substantially the same as shown in Figs. 1 to 4, except that the water-passages are arranged difl'erently. Instead of there being a continuous water passage or chamber about the top of the pipe C the water-space is divided horizontally into a series of water-passages below the air-passages 18 by vertical partitions 20, and the water from the pipe C enters these passages through opening 21 at one side of the top of the pipe C and then passes through water-passages 22 below the air-passages 18 in the same manner as above described in connection with the air-passages. In Figs. 5, 6, and 7 the feathered arrows show the course of the water and the and that in condensers of the general class of that shown the air and water passages may 1 :bearranged in any other suitable manner within the broader features of the invention, so as to secure the desired contact of the air with liquid-cooled surfaces in the air-chamber, and that widely-different forms of air and water passages may be used for this purpose. Thus I have shown in Fig. 8 for purpose of illustration spiral .airpassages 18, through which the air is conducted in a spiral course from the inlet 12 to the outlet 19, and the same spiral arrangement ofwater-passages may be used in place of those shown in Figs. 5 and 7. The air-chamber and condensing-water pipe may be otherwise arranged also, this depending somewhat on the style of condenser to which the invention is applied. .The particular arrangement shown, however, is claimed as a specific feature'of the invention.
